Description

The nifi-property-protection modules include a large number of transitive dependencies as a result of leveraging libraries from different service providers. These dependencies can result in runtime conflicts due to the lack of isolation when loading classes. Both the bootstrap and framework modules depend on these modules. The loading approach should be refactored to implementation isolated loading in order to avoid runtime conflicts.
